IMPROVEMENT IN BUTTONS.

Specification forming part of Letters Patent No. 174,1 6l, datedFebruary 29, 1876; application filed January 17, 1876.

To all whom it may concern Be it known that I, JOSEPH R. SMITH, ofWaterbury, in the' county of New Haven and State of Connecticut, haveinvented a new Improvement in Buttons; and I do hereby declare thefollowing, when taken in connection with the accompanying drawings andthe letters of reference marked thereon, to be a lull, clear, and exactdescripton of the saine, and which said drawings constitute part of thisspecilication, and represent, in

`Figure 1, perspective view of the rear of the button Fig. 2, centralsection.

This invention relates toan. improvement in fabric-covered buttons, andsuch as are constructed with a fabricated protuberance .on

strength of the closing to retain the fabric.`

rlhe center of this rear fabric protrudes through a perforation in theback, to afford means for securing the button; hence all the strainbrought upon the button comes upon this labric, and it frequentlyhappens that it is drawn out .so as to loosen or free the button.

The object of this invention is to' prevent the possibility of thedrawing out or displacement of the fabric; and it consists of a seriesof inward perfor-ations, forming a roughenedinner holding-surface in theback of the button, to form a burr on this disk, to enter the fabricbetween the disk and the lining, so as to se! center is placed betweenthe rear disk and the filling c, then all closed together at the rearedge, so as to securely bind the parts. Usually the disk b has been leftplain, depending upon the friction between the disk b and the lling tohold the fabric e.

ln this improvement numerous perforations, f, are made into the disk bafter the button is closed, or in the process of closing, so as to formburrs upon .the inside, entering or engaging with the fabric. 'lheseburrs so lirmly hold the fabric as to preyent the possibility of itsdisplacement; hence the button is greatly strengthened and itsdurabilityA increased.

l claim- An improvement in the manufacture of covered buttons,consisting of the perforations in the rear disk, whereby the inner. orholding surface of the disk is roughened', substantially as and for thepurpose set forth.
